Specification forming part of Letters Patent No. 35,523. dated June l0,1862.

T0 all whom it nmycozwern:

Be it known that I, GEORGEJONEs, `of

Peekskill,` inthe Stateof New York, have i11- vented a new and usefulmachine entitled an Improved Vindow-Sash Fastener, the object Of whichis to secure window-sash within so as to preventtheir being opened fromwithout, and to draw them tight l so as to prevent their rattling,815e.; and I do hereby declare that the following is aclear, full, andexact description of the construction and Operation Of the same,reference being/had to the annexed drawing, making `a. part of thisspecification.

In the annexed drawing, A. represents the upper sash, to which one pieceof my fastener, p a, 1s screwed; and B represents the lower sash,

r tO which the other piece, I), is screwed.

`l represents an inclinedplane at an angle Of forty-live degrees, orthereabout, and hh hare notches cut thereinand running horizontallyacross it and parallel to eachother.

c represents the yoke or clasp moving on a hinge, 1J, and acting on theinclined plane l, anld catching into and rest-ing in the notches h th.

' The figure in red .ink represents the yoke thrown back, leaving thesashifree from its action. c represents the same as it acts on theinclined plane `and fastens the sashes together.

" Wheneverthe yokeo is pressed down the inclined plane Z, it catches Orfastens itself into the lowest notch it can reach, and thus firmly yokesthe upper and lower sash together and prevents the sash from being movedor the window Opened.` If the sashes do not lt closely together, andaspace intervenes from shrink- `ing or warping of the wood,thusadmitting` dust and air into the room and causing the sashes to clatterand `iar against each other in windy weather, the yoke can be vpresseddown the inclined plane, so as todraw the'sashes together in perfectcontact, thus closing the aperture and effectually preventing al1rattling or jarring. lf the sash should sag and be drawn by warping ofthe wood, settling of the house, or other cause from its originalposition, this does not mar in the least the action of my fastener, thusshowing its superiority Iover al1 other windowfasteners, the parts ofwhich can only act from one sash on the other in a plane or level, andwhich, as soon as this level is impaired, become unable to'act anduseless.

The notches 7L 7L h may be increased to any fast-ener and securing theeffects above described. a

GEO. JONES.
